Kouchi Gari (small inner reap) is a fundamental judo technique that has become essential in modern BJJ and no-gi grappling. The technique involves hooking your opponent’s inside leg with your own while simultaneously breaking their balance backward and to the side. Unlike its larger cousin Ouchi Gari, Kouchi Gari focuses on a smaller, more nuanced reaping motion that targets the ankle and lower calf rather than the thigh. This makes it particularly effective when your opponent has a narrow stance or is stepping backward. The technique’s beauty lies in its timing and subtlety—when executed properly, your opponent falls before they realize they’ve been swept.
Kouchi Gari works exceptionally well as part of combination attacks, often setting up other throws or creating opportunities for guard pulls when the initial attempt is defended. The defensive reactions it provokes—stepping back, widening stance, hopping—each open direct pathways to follow-up techniques like Osoto Gari, Uchi Mata, or Deashi Harai. This makes Kouchi Gari one of the highest-value opening attacks in the standing phase, even when the throw itself does not land cleanly.
From a biomechanical perspective, the technique succeeds because the upper body controls generate approximately 70% of the throwing force through push-pull kuzushi, while the reaping leg simply removes the final support from an already compromised base. Practitioners who understand this principle achieve dramatically higher success rates than those who focus primarily on the leg action.

Playing as Attacker
Key Principles
-
Off-balance opponent diagonally backward before attempting the reap
-
Target the ankle and lower calf, not the thigh
-
Maintain upper body control throughout the entire movement
-
Time the reap when opponent’s weight is on the target leg
-
Drive through the technique rather than pulling backward
-
Keep your base leg strong and stable during execution
-
Follow your opponent to the ground to establish top position
Execution Steps
-
Establish grips and angle: Secure a high collar grip with your right hand and sleeve or wrist control with your left (or equiva…
-
Break opponent’s posture: Pull your opponent’s upper body forward and slightly downward with your collar grip while simultaneo…
-
Create diagonal off-balance (kuzushi): Push and pull in opposite directions with your hands to turn your opponent’s shoulders and hips. Pul…
-
Step in with base leg: Step your left foot (base leg) deep between your opponent’s legs or just outside their lead leg, pos…

Execute the reap: Hook your right foot behind your opponent’s right ankle, making contact with the blade of your foot …
-
Drive and finish to top position: Continue driving forward with your hips and chest while simultaneously reaping backward with your ho…
Common Mistakes
-
Attempting to lift or sweep with only the reaping leg without upper body kuzushi
- Consequence: Opponent easily hops over the attack or posts their leg back, completely nullifying the technique and potentially exposing you to counter throws
- Correction: Focus on upper body off-balancing first; the reap simply removes the base from an already off-balanced opponent. Your hands do 70% of the work.
-
Reaping too high on the leg at the knee or thigh
- Consequence: The technique becomes a weak Ouchi Gari attempt that lacks the precision and leverage of either technique, allowing opponent to easily counter or step out
- Correction: Target the lower calf and ankle specifically. The technique name literally means ‘small’ inner reap—keep the contact point low on the Achilles area.
-
Standing too far away when executing the reap
- Consequence: Loss of upper body control and leverage, making it easy for opponent to maintain balance, counter-grip, and initiate their own throws
- Correction: Step deep with your base leg so your hips are close to your opponent’s hips. You should feel chest-to-chest contact before the reap begins.
Playing as Defender
Key Principles
-
Maintain upright posture and active grip fighting to deny the diagonal kuzushi needed for the throw
-
Keep weight distributed evenly across both feet rather than loading heavily onto one leg
-
React to the initial pull, not the reap—if you wait until you feel the foot hook, it is already too late
-
Use circular footwork to deny your opponent the angle they need for the diagonal off-balance
-
Convert defensive reactions into immediate counter-attacks rather than passively resetting to neutral
Recognition Cues
-
Opponent pulls your collar or neck diagonally while simultaneously pushing your arm across your body, creating a twisting kuzushi toward your rear corner
-
Opponent steps their base foot deep between your legs or to the outside of your lead leg, closing distance rapidly with a bent knee
-
You feel your weight shifting unexpectedly onto one foot as opponent’s grip configuration changes from neutral fighting to committed pulling
-
Opponent’s body angle changes from square to approximately 45 degrees relative to you, indicating they are loading for a turning throw
Defensive Options
-
Retract the targeted leg by stepping it back quickly while simultaneously pushing opponent’s shoulder to break their grip angle - When: As soon as you recognize the diagonal pull and feel the opponent’s base leg stepping in, before the reap makes contact
-
Widen stance and drop hips low while breaking the collar grip with your free hand to deny the off-balance - When: When you feel the initial diagonal pull but before the opponent has stepped in with their base leg
-
Counter with your own Kouchi Gari or Kosoto Gari on the opponent’s base leg as they commit to the throw - When: When opponent has fully committed to the reap with their attacking leg, leaving their base leg momentarily loaded and stationary
Position Integration
Kouchi Gari serves as a critical bridge between standing and ground positions in modern BJJ. From the standing clinch position, successful execution typically leads directly to side control or knee on belly, establishing immediate top pressure. When defended, Kouchi Gari naturally chains into other standing techniques like Osoto Gari, Deashi Harai, or transitions to front headlock position if the opponent sprawls. The technique is particularly valuable in the modern competitive landscape where takedown proficiency separates medal contenders from the field. For guard-oriented players, Kouchi Gari provides the ability to dictate engagement terms rather than conceding the standing phase entirely. Cross-training practitioners benefit enormously, as the technique translates directly from judo randori into BJJ competition and no-gi grappling contexts.
